摘　　要：硫化氢是石油伴生气中的有害成分。目前,关于油田伴生气中硫化氢的成因存在不同观点。本文将以文明寨油田为研究对象,通过文明寨地质环境条件下硫酸盐还原菌生成硫化氢实验,结合文明寨油田地层岩心矿物、地层流体、硫元素的来源等结果,分析地层生成硫化氢的必要条件,探讨油田生产过程中硫化氢产生的机理及途径,从而排除生物降解、热化学成因机理生成硫化氢的可能,证实了硫酸盐还原菌是文明寨油田生成硫化氢的生物成因。Hydrogen sulfide is a harmful component in petroleum associated gas.There are different views on the ori?gin of hydrogen sulfide in associated gas.Taking wenminzhai oilfield as the research object,the experiment of produc?ing hydrogen sulfide by sulfate-reducing bacteria under the geological condition of wenminzhai oilfield had carried out,combining with core mineral formation,formation fluid,wenminzhai oilfield sulfur source and formation condi?tions of hydrogen sulfide to conduct comprehensive analysis and research.The necessary conditions for formation of hydrogen sulfide in formation were analyzed.It discussed the mechanism and way of hydrogen sulfide generation in oilfield production,thus eliminating the possibility of biodegradation and thermochemical genesis,and proved that sulfate reducing bacteria was the biological origin of hydrogen sulfide generation in wenwenzhai oilfield.
